Description

Technical Field

[0001] The present application relates to the field of stopper and cap installation in a container filling production line, and in particular to a stoppering device and a filling equipment. Background Art

[0002] In the container filling production line, containers (such as vials) are transported to a specific station for quantitative filling. After filling, the container needs to be promptly installed with a stopper to seal it in order to maintain the timeliness and sterility of the liquid medicine or other substances in the container.

[0003] See also Figure 1 The plugging device that the inventor has learned mainly includes a plug suction disc 910 and a plug feeding tooth plate 920 attached to the plug suction disc. The plug suction disc 910 is provided with a plug suction hole 911, and the position of the plug suction hole corresponds to the tooth bottom 921 of the plug feeding tooth plate. The plug feeding tooth plate 920 incorporates the plug cover 400 into its tooth bottom 921, and the plug cover 400 is adsorbed by the plug suction disc 910 to play a role in sorting and positioning. The plug suction disc 910 or the container is then raised and lowered by a cylindrical cam (not shown in the figure) to realize the rotary plugging function. Its main problems include: 1. The scope of application is limited, and a plug feeding tooth plate 920 is only suitable for plug covers of a specific size; 2. Before each production, it needs to be disassembled and sterilized with wet heat. The plug suction disc 910 is large and heavy due to the air chamber, and it is inconvenient to disassemble; 3. During the production process, the plug suction disc 910 rotates continuously, and there is friction between the matching contact parts, which easily generates friction dust and related particulate matter, affecting the production environment.

[0047] The exemplary embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, rather than to exhaust all feasible ways of the present application, nor to limit the scope of the present application.

[0048] The embodiments of the present application provide a plugging device and a filling equipment.

[0049] Referring to Figure 2 and Figure 6 , the plugging equipment provided by the embodiments of the present application may include a main shaft 100, a power component and a swing arm 200. The power component controls the rotation and lifting of the main shaft 100, and the swing arm 200 is fixedly connected to the main shaft 100, and a plurality of plug suction heads 300 are detachably arranged on the swing arm 200. By rotating and lifting the main shaft 100 and controlling the vacuum adsorption force of the plug suction head 300, the plug suction head 300 can adsorb the plug cover 400 from the first station and move to the second station, then align with the container mouth to release and press the plug cover 400, completing the plugging action.

[0050] Exemplarily, referring to Figure 6, the plug-taking point 510 is taken as the first working station, and the plug-inserting point 520 is taken as the second working station. To adapt to the movement of the plug-inserting device and the horizontal arrangement of the containers 530 at the plug-inserting point 520, multiple plug caps 400 at the plug-taking point 510 can be arranged obliquely relative to multiple plug caps 400 at the plug-inserting point 520.

[0051] The working principle of the plug-inserting device provided by the embodiment of the present application can be as follows: When the swing arm 200 is at the first working station, the plug-sucking head 300 adsorbs the plug cap 400. The swing arm 200 rotates with the main shaft 100 to the second working station, and after descending to insert the plug cap 400 into the container 530, the plug-sucking head 300 releases the plug cap 400, and the swing arm 200 rises and returns to the first working station.

[0052] Further, referring to Figure 2 , the plug-inserting device may include a plug-sucking head mounting plate 310. The plug-sucking head mounting plate 310 may be a strip-shaped plate for mounting multiple plug-sucking heads 300 in a row. The plug-sucking head mounting plate 310 is detachably connected to the swing arm 200. The plug-sucking head 300 may be, for example, a pagoda joint and is threadedly connected to the plug-sucking head mounting plate 310. A certain plug-sucking head 300 that needs to be replaced can be replaced individually, or multiple plug-sucking heads 300 can be replaced in a group by replacing the plug-sucking head mounting plate 310. Of course, the plug-sucking head mounting plate 310 may not be provided, and the plug-sucking head 300 may be directly mounted on the swing arm 200.

[0053] Further, the plug-inserting device may include an air pipe joint mounting seat 320, on which multiple vacuum air pipe joints 330 arranged neatly may be provided. The vacuum air pipe joints 330 may be threadedly connected to the air pipe joint mounting seat 320. Multiple plug-sucking heads 300 and vacuum air pipe joints 330 can be connected to each other one by one through vacuum air pipes 340.

[0054] In the embodiment of the present application, each plug-sucking head 300 is independent of each other, and the functions of grasping and placing the plug cap 400 are completed through vacuum adsorption. When plug caps 400 with relatively large differences in operation models need to be operated, rapid matching can be achieved by adjusting the negative pressure value or matching plug-sucking heads 300 of corresponding specifications. When sterilization cleaning is required, only the plug-sucking head 300 needs to be removed for cleaning and sterilization, instead of removing the entire suction disc as in the prior art, which is simple to operate and has strong adaptability.

[0055] The head of the air pipe joint mounting seat 320 may be conical to avoid blocking the flowing gas in the production environment. The air pipe joint mounting seat 320 may have a hollow cavity to facilitate the arrangement of pipelines. The air pipe joint mounting seat 320 may be threadedly connected to the swing arm 200, and an O-ring seal may be provided, for example, on the end face where the air pipe joint mounting seat 320 contacts the swing arm 200. The material of the vacuum air pipe 340 may be medical-grade polytetrafluoroethylene (PTFE), which is corrosion-resistant and durable.

[0056] Further, a circular hole can be milled at one end of the swing arm 200 (for example, Figure 2 the left end) for fixed connection with the main shaft 100. The other end of the swing arm 200 (for example, Figure 2 the right end) is connected to the suction plug head 300 or the suction plug head mounting plate 310. An axial seal cover 110 can be provided at the position where the main shaft 100 is connected to the swing arm 200, and the axial seal cover 110 is located on the lower side of the swing arm 200. The axial seal cover 110 can be a part of the shaft collar type, and a shaft sleeve 120 can be provided on the lower side of the axial seal cover 110. The first pressing plate 810 of the corrugated sleeve (introduced later) can be connected to the shaft sleeve 120. The axial seal cover 110 and the shaft sleeve 120 can be positioned and connected by bolts, positioning pins, etc. A bearing capable of bearing axial load can be provided between the main shaft 100 and the axial seal cover 110. So that the main shaft 100 can drive the axial seal cover 110 and the shaft sleeve 120 to lift and can rotate relative to the axial seal cover 110 and the shaft sleeve 120.

[0057] In an embodiment of the present application, referring to Figure 3 , a main shaft lifting assembly 600 can be connected to the main shaft 100. The main shaft lifting assembly 600 can include a lifting lead screw 610 and a lifting lead screw nut 620. The lifting lead screw 610 is rotatably connected to the lifting lead screw nut 620, and the lifting lead screw nut 620 is connected to the main shaft 100. When the lifting lead screw 610 rotates, the lifting lead screw nut 620 and the main shaft 100 can be controlled to lift.

[0058] Further, referring to Figure 2 、 Figure 3 , the main shaft lifting assembly 600 can further include a slide rail mounting seat 630 and a lifting lead screw mounting seat 640. The upper and lower ends of the slide rail mounting seat 630 can be installed with the lifting lead screw mounting seat 640 ( Figure 3 the upper lifting lead screw mounting seat 640 in the middle is not shown), and the lifting lead screw 610 can be rotatably connected to the lifting lead screw mounting seat 640 through, for example, a bearing.

[0059] Further, referring to Figure 3 , the main shaft lifting assembly 600 can further include a slider 631, a slide rail 632 and a lifting plate 650. The slider 631 is connected to the lifting lead screw nut 620. For example, the slider 631 is connected to the lifting plate 650, and the lifting lead screw nut 620 is connected to the lifting plate 650 through its mounting seat to realize the connection between the slider 631 and the lifting lead screw nut 620. The slide rail 632 is provided on the slide rail mounting seat 630 and its extending direction is the up and down direction. The slider 631 is slidably provided on the slide rail 632 to make the trajectory of the lifting lead screw nut 620 stable and durable. A second connecting plate 132 of the main shaft can be fixedly provided on the main shaft 100, and the second connecting plate 132 of the main shaft and the lifting plate 650 can be fixedly connected. When the lifting plate 650 lifts, the main shaft 100 can lift accordingly.

[0060] Further, referring to Figure 2 , the main shaft lifting assembly 600 may further include a servo motor 660 for lifting, a speed reducer 670, and a coupling 680 for lifting. The servo motor 660 for lifting is connected to the lead screw 610 for lifting through the speed reducer 670 and the coupling 680 for lifting and controls its rotation.

[0061] In an embodiment of the present application, referring to Figure 4 and Figure 5 , a main shaft rotation assembly 700 is connected to the main shaft 100. The main shaft rotation assembly 700 includes a lead screw 710 for rotation, a lead screw nut 720 for rotation, and a first main shaft connecting plate 131. The lead screw 710 for rotation is rotatably connected to the lead screw nut 720 for rotation. One end of the first main shaft connecting plate 131 is fixedly connected to the main shaft 100, and the lead screw nut 720 for rotation is rotatably connected to the other end of the first main shaft connecting plate 131. Here, the rotation axis of the lead screw 710 may be perpendicular to the rotation axis of the first connecting plate 131 relative to the lead screw nut 720. After the lead screw 710 for rotation rotates, it drives the lead screw nut 720 for rotation to advance or retreat along the extension direction of the lead screw 710 for rotation (as indicated by the double arrow in Figure 5 ), and drives the main shaft 100 to rotate reciprocally through the first main shaft connecting plate 131. Through innovative design, the present application converts the reciprocating linear motion of the lead screw nut mechanism into the reciprocating rotation of the main shaft 100, with high precision and capable of achieving accurate station conversion.

[0062] Further, the main shaft rotation assembly 700 may further include a rotating core shaft 760 and a third main shaft connecting plate 133. One end of the third main shaft connecting plate 133 is fixedly connected to the main shaft 100, and the lead screw 710 for rotation is hinged to the other end of the third main shaft connecting plate 133 through the rotating core shaft 760.

[0063] Further, the main shaft rotation assembly 700 may further include a servo motor 730 for rotation, a servo motor coupling 740 for rotation, and a coupling mounting seat 750. The servo motor 730 for rotation is connected to the lead screw 710 for rotation through the servo motor coupling 740 for rotation to control its rotation. The coupling mounting seat 750 may be a hollow square box-like part. Two circular connecting parts 770 may be provided on the side of the coupling mounting seat 750, and the rotating core shaft 760 passes through the two connecting parts 770 so that the coupling mounting seat 750 is rotatably connected to the rotating core shaft 760. The main shaft 100 is then connected to the rotating core shaft 760 through the third main shaft connecting plate 133 to achieve the hinge connection between the main shaft 100 and the coupling mounting seat 750, enabling the position of the lead screw 710 for rotation to be finely adjusted to avoid interference. It can be understood that the second main shaft connecting plate 132 and the third main shaft connecting plate 133 may be an integrally formed structure.

[0064] Of course, reciprocating motion can also be achieved by replacing the lead screw and lead screw nut with a timing belt, a timing belt pulley or a gear.

[0065] In an embodiment of the present application, referring to Figure 2 , the stopper device includes a main shaft base 140 and a substrate 150. The main shaft base 140 is sleeved outside the main shaft 100 and fixedly connected to the substrate 150. The main shaft 100 passes through the substrate 150, and the swing arm 200 and the power component are respectively arranged on the upper and lower sides of the substrate 150. By separating the power component and the swing arm 200 with the substrate 150, it is possible to minimize the transfer of contamination from the lower part to the upper part that needs to be stoppered.

[0066] Furthermore, a telescopic bellows 800 can be arranged between the main shaft base 140 and the swing arm 200. The bellows 800 can be a soft part such as silicone. The stopper device can include a first bellows pressing plate 810 and a second bellows pressing plate 820. The first bellows pressing plate 810 is connected to the sleeve 120, and the second bellows pressing plate 820 is connected to the main shaft base 140. It can be understood that when the main shaft 100 moves up and down and rotates, friction will be generated with the corresponding rotating components. Therefore, lubricating substances such as lubricating oil are usually arranged on the main shaft 100. The arrangement of the bellows 800 can not only prevent oil stains from being exposed to the production environment, but also improve the aesthetic degree.

[0067] The filling equipment provided by the embodiment of the present application includes the aforementioned stopper device.

[0068] The above are the preferred embodiments of the present application. It should be noted that for those skilled in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
